Weapons cache found at Las Vegas shooter’s home

(CNN)Stephen Paddock, who sent bullets and terror down on thousands attending a Jason Aldean concert in Las Vegas, had an arsenal in his 32nd-floor hotel room and at his home 80 miles away, officials said.

Authorities said Paddock killed 59 people and injured another 527 early Monday in the deadliest mass shooting in modern US history.

In the hours after the retired accountant committed the shooting, authorities rolled out frightening new details, including the discovery of scopes on rifles at the resort and explosives at his home.

But what they couldn’t explain is why the man who had never faced any notable criminal charges did it. There was no known motive late Monday.

Even Paddock’s brother had no answers.

“We’re still just completely befuddled. Dumbstruck,” Eric Paddock said in Orlando, Florida.

‘Everyone’s dying around me’

Witnesses described the horror that unfolded.

Taylor Benge said he “could see a guy with a bullet wound right in his neck, motionless,” several feet away. “From there on … people just started dropping like flies.”

Alexandria Cheplak, 25, called her father as she ran from the bullets.

“Everyone’s dying around me,” Jon Cheplak recalled her saying. “Everyone’s dying. They shot my friend … I’ve got to get out of here.”

Police said Paddock, unleashed a hailstorm of bullets from the 32nd floor of the resort, Lombardo said Monday.

Authorities are still piecing together a motive.

“I can’t get into the mind of a psychopath,” the sheriff said.

Mayor Carolyn Goodman described the gunman as “a crazed lunatic full of hate.”

Festival turns into massacre

Deadliest mass shootings in modern US history

Benge lauded the heroics of his sister, who “threw herself on top of me and said, ‘I love you, Taylor,'” he said.

“Even after an hour and 30 minutes, I didn’t know if I was safe.”

Witness Bryan Hopkins said he survived by jumping into a walk-in freezer at the Mandalay Bay hotel.

“There must have been, I don’t know, 23 to 30 of us inside this freezer,” he said.

So far, the massacre has no known link to overseas terrorism or terror groups, a US official with knowledge of the case said.

And a woman who was described as a “person of interest” after the attack is now not believed to be involved in the shooting, police said in a statement.

“Marilou Danley is no longer being sought out as a person of interest,” the Las Vegas Metropolitan Police Department said. “LVMPD detectives have made contact with her and do not believe she is involved with the shooting on the strip.”

The gunman’s brother, Eric Paddock, said he was stunned to learn Stephen was believed responsible.

He described his brother, a retired accountant, as “a wealthy guy. He liked to play video poker. He went on cruises.”

The last time Eric Paddock spoke to his brother was when Stephen texted him, asking how their mother was doing after losing power from Hurricane Irma.

Eric Paddock said he knew his brother owned a few handguns and maybe one long rifle, but said he did not know of any automatic weapons.

Maloney told CNN she also gave transportation to anyone who needed it after the attack.

“I just started picking people up and giving people rides,” she said.

Aldean posted a statement on Instagram saying that he and his crew were safe.

“My Thoughts and prayers go out to everyone involved tonight. It hurts my heart that this would happen to anyone who was just coming out to enjoy what should have been a fun night,” he wrote.
